Specification of Letters Patent.

Patented Feb. 1, 191% Application filed June 5, 1909. Serial No.500,450.

To all whom it may concern:

Be it known that I, CHARLES H. Coon, a citizen of the United States, anda resident of Saugerties, in the county of Ulster and State of New York,have invented a new and Improved. Automatic Adjustable Reel, of whichthe following is a full, clear, and exact description.

This invention relates to the art of paper making, but it is applicablein any industry in which the web, such as paper or similar manufacturedproduct, is wrapped upon the reel. In the manufacture of the paper,where the paper is to be formed into sheets it is rolled upon the reeland the diameter 01 the reel increases with each layer of paper which iswrapped upon it. When the paper is cut into sheets on the reel, thesheets which are formed by the inner layers are of shorter length thanthe sheets formed by the outermost layers of the material. sheetsmust'be afterward trimmed to a uniform dimension so that a loss ofmaterial is entailed.

The object of this invention is to produce a reel in which the virtualdiameter of the reel remains substantially constant. In other words, thediameter of the reel reduces itself automatically as the web of materialwraps upon it. In this way the length of material wrapped upon the reelin one revolution remains constant, and when the material on the fullreel is out, the sheets will all have the same length.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an end elevation of a reel constructed according to myinvention, certain parts being broken away and shown in section; Fig. 2is a longitudinal vertical section through the upper portion of thereel, further illustrating the details of its construction; Fig. 3 is adetail view of a diagrammatic nature, illustratin the manner in whichthe reel adjusts itseli as the layers of material wrap upon it; and Fig.t is an The edge view showing a pad of paper supposed to have been cutand taken from the reel.

Referring more particularly to the parts, the frame 01 the machinecomprises two oppositely disposed standards 1, 1, and these standardssupport a horizontal shaft 2 rotatably. Each end of this shaft isprovided with a spider 3 having radially projecting arms 1-. These armsare in the form of channels presenting inwardly projecting flanges 5which operate as guides for blocks 6 which are mounted to slidelongitudinally in the channels. The web oi each arm is provided with alongitudinal slot 7, and each block is connected to this slot by anadjusting bolt 8. Near the outer face of each block, a guide stem 9 isrigidly attached. These guide stems extend through openings 10 which areformed in the side bars 11 of the reel. On the stems 9, coil springs 12are placed, and these springs tend to force thebars outwardly on theguide stems if the bars should be displaced inwardly from their normalposition. The normal position of the bars is shown in Fig. 2, and itwill be noted that the extremities of the stems 9 project well beyondthe bars.

On the outer sides of the bars 11, clutches 13 are arranged. Each ofthese clutches comprises a base plate 14. which is mounted on the outerside or the bar, and in this base plate 14 a slide 15 is mounted in adove'tail groove. The slide 15 is formed with a post 16, and to thispost 16 a clutch arm 17 is pivotally attached. The outer end of theclutch arm is formed with an eye 18 through which the projectingextremity of the stem passes. Between the stem and the pivot point 16, aspring 19 is provided, and the lower end of this spring is attached tothe bar, the upper end being attached to the clutch arm. The opening 18is slightly larger than the diameter of the stem, and the arran ementdescribed is such that the clutch will permit an inward movement 01 thebar, but will lock the bar against returning.

Above the standards 1, 1, housings 20 are provided, and in these housins 20, adjustmg screws 21 are mounted, assiown. These adjusting screwsare provided at their upper ends with bevel gear wheels 22, and thesebevel gear wheels 22 mesh with similar bevel gear wheels 23, operated bya shaft 24, l said shaft having a hand-wheel for rotat ing the same. Onthe screws 21, boxes 26 are arranged, said boxes making a threaded jengagement with the screws so that when the screws are rotated, theboxes will be adjusted r and maintained in alinement with each other.These boxes 26 form end bearings for a roller shaft 27. This rollershaft. is provided at intermediate points on its length with rollers 28,and the lower faces of these 1 rollers determine the position of thebars 11 as they pass the shaft 27. In other words, the diameter of thereel is determined by the j position of the shaft 27. If it is desiredto 5 reduce the diameter of the reel, it is neeessary to lower the shaft27 and adjust the blocks 6 inwardly to adapt the stems to the smallerdiameter. As the bars engage the rollers 28, they are depressed or slidin- .j wardly on their stems and the clutches 13 lock them againstsliding outwardly under the force of their springs 12. Near the rollers28, guide cleats 29 are provided, which are engaged by the edges of theweb of paper or other material, so as to guide it into a mid-position onthe reel.

The web of paper, or similar material, is wrapped upon the reel in themanner indicated by the dotted lines in Fig. 1. The web passes onto thereel at its upper side and 1 under the rollers 28. It should bedistinctly understood that in the wrapping operation, the rollers 28rotate upon a fixed axis. As i the layers of the web accumulate on thereel, 1 the bars 11 become displaced inwardly and are maintained in thisinwardly displaced relation by the clutches 18. After a desired amountof the web has been wrapped upon the reel, the reel can be out along theedge of one of the bars 11, and the material upon the reel can then beremoved so as to present a pad 30. The mode of operation of the reel inthis connection is clearly shown in Fig. 3, where the bars arerepresented in dotted lines displaced inwardly, as suggest- 1 ed. Thematerial between the bars on the inner side will tend to bag inwardly,as

illustrated by the dotted lines 31. l/Vhen the pad 30 of paper, orsimilar material, has been formed as described, the sheets will all havethe same length, as indicated in Fig. 4:, but if the pad had been formedon a reel of fixed diameter and in which the virtual diameter wouldincrease continuously, the 1 sheets would not have the same length, but

' one edge of the pad would be tapered, as

indicated by the dotted line 32 in Fig. 4, if the opposite edges of thesheets were all j alined together, as will be readily under- 1,

stood. This reel evidently prevents a waste of the triangular block orwedge of material which would be cut from the edge of the pad'at theinner end of the dotted line 32.

Special attention is called to the slide 15 l carrying the pivot postfor the clutch. This character of mounting seems to be a necessaryfeature of the clutch mechanism as it enables the clutch arm to adjustitself to the stem and insures efliciency of the clutch.

Having thus described my invention, I. claim as new and desire to secureby Letters Patent,-

l. A reel of the class described, having spiders with substantiallyradially disposed guide members, longitudinal bars mounted on said guidemembers and adapted to slide inwardly thereupon, and means for lockingsaid bars against return when moved inwardly.

2. A reel having a plurality of longitudinally disposed bars, guiderollers cooperating with said bars and aifording means for guiding a webof material to wrap upon said reel, said rollers affording means fordisplacing said bars inwardly as the layers of material accumulatethereupon, and means for locking said bars against a return outwardmovement when displaced inwardly.

3. A reel having rotatable spiders, bars extending longitudinally, meansfor guiding i said bars on said spiders in a radial direction, resilientmeans tending to force said bars outwardly, members cooperating withsaid bars to force the same inwardly as the layers of materialaccumulate thereupon, and means for locking said bars against an outwardmovement after being displaced inwardly.

L. A reel having substantially radially projecting guide stems, barssliding on said guide stems, clutches carried by said bars and adaptedto prevent an outward movement thereof, and means for guiding a web ofmaterial on said reel.

5. A reel having substantially radial guide stems, bars mounted on saidguide stems and adapted to slide inwardly, resilient means tending toforce said bars outwardly, clutches carried by said bars locking thesame against an outward movement on said stems, and means cooperatingwith said bars to displace the same inwardly when the layers of the webwrap upon the reel.

6. A reel having substantially radial stems, bars slidably mounted onsaid stems, springs tending to force said bars outwardly on said stemsand resisting their inward movement, clutches mounted on said barshaving pivoted clutch arms with eyes through which said stems project,said clutch arms affording means for locking said bars against outwardmovement and permitting the free inward movement of said bars, andmembers cooperating with said bars to displace the same inwardly as theweb of material wraps upon the reel.

7. A reel having substantially radial Maser guide stems, bars slidablymounted on said I gulde stems and adapted to be dlsplaced inwardly,springs tending to force said bars outwardly, slides mounted on saidbars and adapted to slide longitudinally with respect to the same,clutch arms pivotally mounted on said slides and having eyes receivingthe extremities of said stems, springs in connection with said clutcharms and constraining l the same to clutch said stems, and memberscooperating With said bars to guide the Web onto said reel and affordingmeans for displacing said bars inwardly as the layers of materialaccumulate thereupon.

, In testimony whereof I have signed my name to this specification inthe presence of two subscribing Witnesses.
